Definitely not for $20,000 or $100,000. If it were $100,000,000 that would be a different story.
I maybe would have accepted 20k if I were in elementary school or something, since a lot of time would be consumed in school, and depending on specific terms I would still have games and the like as a hobby.

I think for most people later in highschool or in college or otherwise employable, it's not likely worth it. You can make more than 20k in 10 years working part time, minimum wage, 4 days a week for around 3 hours a day, and you don't need to give up any hobbies, rather you can spend more on them if you want. Even 100K, though better, isn't that much better in my opinion, to give up one of my main pastimes for 10 years.
